What is Generics in C#? Example.

Generics allow you to define the specification of the data type of programming elements in a class or a method, until it is actually used in the program. 

In other words, generics allow you to write a class or method that can work with any data type. 

Example 

class Program
    {
        static void Main(string[] args)
        {
            int [] ar={10,20,30,50,80,60};
            string [] ar1 = { "kul","amit","soham"};
            Student.Show(ar);
            Student.Show(ar1);
            Console.ReadLine();
        }
    }
    static class Student
    {
        public static void Show<T>(T [] ar)
        {
            for (int i = 0; i < ar.Length;i++ )
            {
                Console.WriteLine(ar[i]);
            }
        }
    }
